Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies require additional equipment beyond HMD wearable devices to accurately measure empathy levels, which is inconvenient and limits the effectiveness of empathy measurement in extended reality environments.
Innovation Solution
A display device that utilizes a sensing unit to obtain movement information from a target user's body parts and a processor to generate extended reality images based on user movements, calculate emotional and physical empathy degrees, and produce a final empathy degree by combining these metrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physiological signals (brain waves, electrocardiogram, skin conductance) are used to measure empathy degrees, then measurement precision is improved, but device complexity increases due to requiring additional equipment beyond HMD wearable devices
Solution Approach 1:
The patent extracts the empathy measurement function from a multi-sensor physiological monitoring system and implements it using only movement sensors already present in HMD wearable devices. By taking out the empathy measurement capability from the complex physiological signal processing system and relocating it to the movement sensor system, the patent achieves accurate empathy measurement without requiring additional equipment.
Solution Approach 2:
The patent uses movement information as a substitute or copy of physiological signals for empathy measurement. Instead of directly measuring brain waves, electrocardiograms, or skin conductance, the system captures movement patterns that correlate with emotional states and uses these movement copies to infer empathy degrees, thereby avoiding the need for complex physiological sensing equipment.
2Measurement precision
If multiple types of sensors (brain wave, electrocardiogram, skin conductance) are deployed to measure empathy, then measurement precision is improved, but ease of operation deteriorates due to requiring additional equipment
Solution Approach 1:
The patent makes the HMD wearable device universal by enabling it to perform both its primary function (displaying extended reality content) and empathy measurement using the same device. The movement sensors in the HMD are utilized for dual purposes: tracking user movements for XR interaction and analyzing movement patterns for empathy assessment, thereby eliminating the need for separate measurement equipment and improving ease of operation.
3Device complexity
If only movement information from HMD wearable devices is used, then device complexity is reduced, but measurement precision may deteriorate compared to using physiological signals
Solution Approach 1:
The patent changes the measurement parameters from direct physiological signals (brain waves, electrocardiogram, skin conductance) to movement-based parameters (head movements, eye movements, body movements). By transforming the measurement approach from internal physiological parameters to external movement parameters, the system achieves empathy measurement using simpler devices while maintaining precision through sophisticated analysis of movement patterns that reflect emotional states.

AI summary
A display device, a wearable electronic device, and an operating method of an electronic device are proposed. According to the proposed technical idea, the display device includes a sensing unit configured to obtain movement information about at least one body part of a target user responding to an extended reality (XR) image output by a display panel, and a processor configured to generate the extended reality image from movements of the target user on the basis of the movement information, calculate an emotional empathy degree and a physical empathy degree for another user on the basis of the movement information the target user and movement information of the other user, and generate a final empathy degree of the target user for the other user on the basis of the emotional empathy degree and the physical empathy degree.
